Pints to Pounds Converter
Convert pints to pounds for water, milk, oil, honey, or gasoline. Choose a US liquid or dry pint and the tool returns weight in pounds, ounces, and grams.
Example: with Volume in pints 1 · Pint type US liquid pint (473.176 mL) · Substance Water (1.00 g/mL) → Weight in pounds: 1.043 lb.
- Weight in ounces16.69 oz
- Weight in grams473 g

Weight = pint volume × density. A pint measures space; pounds measure mass, so the substance's density sets the answer.
Why a pint isn't a fixed weight
A pint measures volume — how much space a liquid fills — while a pound measures mass. The bridge between them is density, the mass packed into each milliliter. Water sits at almost exactly 1.00 g/mL, so a US liquid pint of 473 mL weighs about 1.04 pounds. Denser liquids like honey at 1.42 g/mL weigh far more per pint; lighter ones like cooking oil or gasoline weigh less.
That is why the old rhyme 'a pint's a pound the world around' only works for water, and even then it rounds down a hair. Pick the substance that matches what you are weighing before you trust the pounds.
Liquid pints versus dry pints
The United States keeps two different pints. The liquid pint is 473.176 mL and is what you buy for milk or beer. The dry pint, used for produce like berries, is larger at 550.61 mL — about 16 percent more volume. Choose the right one, because the gap changes the pounds noticeably.
For packed solids such as berries or flour, treat the density figure as a rough average. Settling, moisture, and how tightly the container is filled all move the real weight around.
How it’s calculated
Weight = pint volume × substance density. One US liquid pint = 473.176 mL; one US dry pint = 550.610 mL. Density is in grams per milliliter, so grams = mL × g/mL. Pounds use 1 lb = 453.59237 g; ounces use 1 oz = 28.349523125 g (NIST).
Densities are approximate and shift with temperature, fat content, and packing — treat the result as a close estimate, not a lab measurement.
Weight of one US liquid pint by substance
| Substance | Density (g/mL) | Weight (lb) | Weight (g) |
|---|---|---|---|
| Water | 1.00 | 1.043 lb | 473 g |
| Milk | 1.03 | 1.074 lb | 487 g |
| Cooking oil | 0.92 | 0.960 lb | 435 g |
| Honey | 1.42 | 1.481 lb | 672 g |
| Gasoline | 0.74 | 0.772 lb | 350 g |
Computed with 1 US liquid pint = 473.176 mL and the listed densities; 1 lb = 453.59237 g. Densities are approximate.
Common mistakes
- Using a dry pint's volume with a liquid-pint figure, or the reverse — they differ by about 77 mL.
- Assuming a pint of any liquid weighs a pound; only water is close, and the saying is a rounding, not a rule.
- Reading packed solids like berries or flour as if their density were uniform — settling changes the mass.
- Confusing ounces of weight with fluid ounces of volume.
Frequently asked questions
How do you convert pints to pounds?
Multiply the pint volume in milliliters by the substance's density in g/mL to get grams, then divide by 453.59237 to get pounds. A US liquid pint is 473.176 mL, so a pint of water weighs about 1.04 pounds.
Does a pint of water weigh a pound?
Almost. A US liquid pint of water weighs about 1.043 pounds, so the rhyme 'a pint's a pound' rounds down slightly. A UK pint is larger and weighs about 1.25 pounds.
What is the difference between a liquid and dry pint?
The US liquid pint is 473.176 mL; the US dry pint is 550.610 mL, roughly 16 percent larger. Dry pints are used for produce sold by volume, like berries.
Why do I need to pick a substance?
Pounds measure weight and pints measure volume, so the answer depends on density. Honey is far heavier per pint than oil, even though both fill the same space.
How many pounds is a pint of blueberries?
A dry pint of blueberries weighs roughly 0.75 pound, but berries settle unevenly, so treat any volume-to-weight figure for produce as an estimate.
